## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-20.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 87/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 664 tokens (~132/item across 5 items; 3 tools + 2 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-09-20 (score 70, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-09-19 (score 69, 0)

## MCP tools (3)

### `categorize_product` (~181 tokens)

Map a free-text product description to a marketplace category path.

Walks the taxonomy of the target marketplace one level at a time and
returns the full path: one match per level, from the broadest category down
to the most specific one, each with the reason it was picked. Use it to
assign a listing category to a product you only have prose for.

The last match carries `truncated: true` when the per-request token budget
stopped the descent before a leaf. Every successful call is billed: with no
\`X-API-Key` header and no x402 payment proof the tool answers with the
payment requirements instead of a result.

Input parameters:

- `description` (string, required): free-text product description, up to 2000 characters.
- `store_id` (string, required): target marketplace, one of the values from `list_stores`.

Output parameters:

- `categories` (array): One match per taxonomy level, from broadest to most specific. The last item may carry truncated=true
- `judge_approved`: Whether a separate LLM judge confirmed the final category path is consistent with the description; null when the token budget ran out before the judge could run
- `judge_reason`: The judge's stated reason for its verdict on the final path; null when the judge did not run or the final path was never judged
- `name` (string): Product name

### `list_stores` (~68 tokens)

List the marketplaces whose taxonomies are loaded, as `store_id` values.

These are the only accepted values for the `store_id` argument of
\`categorize_product`. Free of charge on purpose: without it an agent would
have to pay for a failed call to discover them.

Output parameters:

- `result` (array)

### `payment_info` (~63 tokens)

Return the x402 payment requirements for one categorization call.

Meant for an agent that holds no API key: gives network, asset, recipient
address and amount as JSON, so the payment authorization can be signed
before calling `categorize_product`. Free of charge.

Output parameters:

- `result` (string)
